What is your question?
I put new air filter in and a week later the back side is saturated with oil from the tubes.
How long has your 1990 Jeep Cherokee had this problem?
2000 miles
Yep - them **auto repair technicians** they got at AutoZone are really smart for sure! Hope you get it figured out. â–ªï¸https://youtu.be/ikKN-s9inJ8â–ªï¸
Also make sure the PCV valve system is functional.
Auto zone parts store tells me there is no PCV valve on this unit. A 90 cherokee 4.0 6.
